Abstract: The present description relates to a flat heat exchanger of the types which use a single working fluid circulating continuously through the inside of one or a plurality of heat transmission conduits for cooling one or more electric or electronic components or the like located in a position close to or in contact with a region of the outer part of at least one heat transmission conduit.

Abstract: Desiccant bag for electronic devices characterized in that it comprises: A first outer bag, made of plastic, hermetically sealed. A second porous bag, housed inside the first bag, leaving a gap between the first bag and the second porous bag, in which an absorbent material or drying product (superabsorbent polymer) is housed. A third porous bag housed inside the second bag, impregnated with an oxygen scavenger material housing the electronic device to be recovered and/or protected wherein the first two bags are crossed by a transverse pipe which has a connection having a bypass which starting from the connection penetrates inside the third bag. A minimization of the drying time, effectiveness in the process by using mechanical and chemical means and effectiveness that can reach 100% are achieved.

Abstract: The present invention provides a sensor assembly for installation within an opening in a wall separating an interior cavity from an exterior. The sensor assembly includes an exterior housing and a cartridge including a sensor. When the cartridge is correctly positioned within the housing, a flow path is established from the interior cavity to the sensor supported within the cartridge. When the cartridge is not positioned within the housing, the flow path is blocked.

Abstract: Reflector that when associated to a portable telephone allows concentrating a maximum amount of radiation, providing a directional radiation source allowing an increased signal gain, greater coverage, reduced radiation on the face of the circuit attached to the telephone and a lower incidence on the human body. The reflector is attached on the casing on the portable telephone, constructed on a fiberglass plate and comprises two faces on which are arranged a number of tracks such that the radiation between the reflector and the portable telephone antenna is adjusted. The support is conformed by the reflector itself, to which are adhered two double strips, one for attachment to the telephone and another for attachment to an ornamental strip that is provided on its outer face with an attachment area and an available area.

Abstract: The present invention relates to a refractory material which consists of 63 to 82 weight percent of SiC, 15 to 27 weight percent of Si.sub.3 N.sub.4 and 3 to 10 weight percent of inorganic oxides.

Abstract: Eyeglass structure which includes a male and female connection of the lens holding rings of the glasses and a band connecting the temple pieces of spring or resilient material to gently grip the sides and rear of the head of a wearer to distribute the load and wherein the plane of the lens holding rings may be adjusted through a range of generally vertical planes.
